WHEEL-PRESS.

Specification of Letters Patent. Patented F b 25 1913 Application filed Februaryxlfl, 1912.

Serial No. 676,930.

To all whom it may concern:

Be it. known that I, HERMAN A. J ENSEN- ms, a citizen of'the United States, residing an axle and to so arrange the press that first one and then another of the wheels can be relnovedfrom the axle in one set-ting. The invention relates 1 to other details which will be fully described hereafter.

. In the accompanying drawings :Figure- 1, is a side view of my improved wheel press Fig. 2, is an end vlew; Fig. 3, is a trans-E verse sectional view on the line 33, Fig; 1; Fig. 4, is a sectional plan view on the line 4'4, Fig. 1; Fig. 5, is a sectional view of the connecting valve; Fig. 6, is a diagram view showing the method of applying a wheel to an axle; and Fig. 7, is a diagram view showing the method of removing the axle from a wheel. Mounted on the base frame A are two heads B, B connected together by upper and lower tie bars C, C, and located centrally between the two heads is'a resistance post D having a longitudinal cavityd in its face in which the axles rest. On the ends of the post are detachable bearing rings d In the heads'B,-B are cylinders'E, E, re spectively, and in these cylinders are plungers F having heads f shaped as clearly shown in Fig. 1 to pass over the ends of the axles and drive the wheels into place. In

each head are recesses f. in which plugs may be placed for'pushing'ofi' different lengths;

of axles.

Adapted to rails aon the base frame A are trolleys Gr, each trolley hasfour wheels 9 in the present instance, adapted to the rails, and the table G is vertically adjust-v able. On each corner of the table of the trolley are vertical screws '9 on which are sprocket wheels. h is a vertical shaft also having a sprocket wheel and a chain passes around the several sprocket Wheels, so that on turning the shaft h the tables G will be raised or low-;

cred. At the upper end Of t e, af is 3L toothed wheel h with which the lever k engages when raised to the horizontal position, so that on turning the lever the sprocket wheels are turned. Thus the tables G can be raised or lowered to accommodate wheels of different diameters, as they support the wheels while being driven on the axles.

The plungers F are attached to chains f leading over .guide wheels to weights F, shown by dotted lines in Fig. 1, so that as soon as the plungers are relieved from pressure they are returned by the weights to the normal posltion; In the present instance there "18 a weight located at the end of each cylinder and attached to the head of each plunger by chains f I,-I are pump cylinders located on each head, and 2', i are the pump plungers operated by eccentrics i from anoverhead shaft- I mounted in bearings supported by the heads B B. "These pumps are of the ordinary construction and need not be further described in detail.

Leading from the pump of the head 13' is a pipe n, which extends to the rear of the cylinder E, and coupled through a pipe n' to this pipe is a pressure and suctioncham-.

ber N. At the intersection of these two pipes is a hand operated valve N which may be turned to'cut off the pipe 41., and connected to the pipe at this point is a blowoff Whistle and pressure gage.

n is a stop valve in the pipe n. The pipe n communicates with the upper end of the chamber N, and a pipe 71. connects the lower end of the chamber with the suction side 0 the pump I. I e

The same construction is duplicated on the head B; m being the pipe leading from the pump to the end of the cylinder; M being the chamber connected at its upper end by the pipe m to the pipe m; M being the hand valve; m the stop valve in the pipe m; and m is a pipe connecting the chamber with the suction side of the pump.

In order to form a communication between the two pipes n and m, I provide a ing one plunger, if the plunger is the one on thehead B thenjthes p valves 11, p

are opened and the stop valve m is closed and valve n opened, then both pumps will force fluid under pressure to the cylinder E in the head B. If the other head is .to be operated by the two pumps then the valve 4& is closed and valve m opened and the chambers N and M are connected to the supply pipes through the pipes n and m, and the two chambers N and M are connected together by a pipe S having a ball valve 8 of the form shown in Fig. 5. The interior of the valve is made as clearly shown in said figure and has a funnel shaped seat at each end. The hard rubber ball 8 normally rests in the bottom of the casing so as to allow the water in the pipes of the closed chambers to freely pass from one chamber to another, but in the event of an excessive pressure in the chamber then the valve will close against one of the seats in the direction of flow of the liquid and will close thepipe leading to the other chamber, but'as soon as the pressure in the two chambers is equal then the valve will fall clear of both seats.

The ump I of each head is'running continuous y'and is connected with-the pressure and suctiontankon'both sides, so that the water circulates throughthe tank and operating. V I

The operation is as follows a-If wheels through the pump when the plunger is not are to be placed upon an axle they are preferably assembled on-the axle and the axle is then mounted in the recess in the post D and thewheelsrest on the platform of the trolleys'G; the platforms having been raised. or lowered to the. desired height. The valves N and M are'turned so as to close the pipes at and m, respectively, and the three-way valves 4) and o are turned to admit air under pressure to the chambers N and M. This will cause the plungers to move quickly forward to the work, .as the liquid will be forced out of the chambers through the pumps and pipes m and -n to.

the cylinders while the pumps will continue to force water under pressure to the rear of the cylinders, and when the valves 1*, o are turned to atmosphere the pressure in the cylinders will increase sufliciently to force the wheels onto the axle as in Fig. 6. hen wheels are to be removed from the axle then a plug a: is placed in the recess 7' in one of the heads 7 so as to rest against the end of the axle and the wheel rests against the ring d of the post D, as in Fig. 7, and, if necessary, the pumps of both heads may supply fluid to the one cylinder. Thus the that it is where only one pump is connected to the cylinder. side ofthe axle is to be removed the operation is repeated at the opposite end of the machine and the pumps will force fluid into the cylinder at that end. I

By this construction I provide a substantial, double-ended wheel press which can be used to simultaneously place both wheels on an axle, or from the axle.

plunger will be moved at double the speed x If thewheel on the other a quickly remove the wheels I The device is compact, readilyoperated, 7

and the platforms of the trolleys can be raised so as to bring the Wheels in proper alinement with the axle. Furthermore the a1r pressure may be used for quickl mov- 1.
